Refreshing Textbox - Does Not Update Reflecting The New Product
Apr 16, 2009I have 3 text boxes that are related on a form. They come from the same dataset and the same table in the dataset. The 3rd textbox is defined in the table as the product of textbox (really the column) 1 and 2. The problem is when I save after changing textbox 1 or 2, 3 does not update reflecting the new product. I have a different form using a different dataset that does a similar setup correctly. What could be the difference between the 2 forms or tables or dataset that I could look for?
View 5 RepliesC# - Update And Get Values In Windows Forms While Moving One Form To Other Form?

Update Excel Files Using .net (Windows Form)?
Dec 3, 2009I have two, soon to be many spreadsheet files. There are cell references between the files which need to be updated. I would write this in a excel macro but these spreadsheets are design tables for Solidworks, a CAD system and it does not allow macro enabled workbooks. So what I would like to do is push a button and open all of the spreadsheets, accept the update workbook prompt then save and close the files.
I've seen a similar command developed by someone using the Soildworks API but updating design tables in solidworks takes ALOT of time to run compared to just opening and closing spreadsheets.I am using Visual Studio 2010 Beta 2 along with Excel 2010 Beta 2 (I like to have the new things)

View 5 RepliesRefreshing DataGrid On Parent Form After A Child Form Has Updated DB?
Dec 3, 2009Basically I have two forms - Form1 has a DataGrid on it (Infragistics) and in the double-click row event it creates an instance of the EditForm and passes along the UniqueId for editing. Once the user saves the changes (if they make changes) - I want the DataGrid on Form1 to refresh. Here is how I thought I could get this to work ... I create a public property called RefreshRequired as boolean. Before unloading the EditForm it sets this property to true. Then Unloads. This continues the code in Form1 (which showed the EditForm as modal) but RefreshRequired is still showing as False? Why isn't my EditForm able to set the property?

VS 2010 - Form.Activated - Refreshing A Form Bound To Different Tables
Feb 4, 2011I had issues in refreshing a form that is bound to different tables in a database. Various forms allow the user to change and add and update information on the form via the database. I had created a public sub in that form that the other forms could call, after saving the data, that was supposed to refresh the data on the main form. This was not working so I researched the problem. I came across this page which pertains to Form.Activated: [url]
I placed all of the table adapter fills into this event, instead of in Form_Load, and it seems to work now, when the form first loads, and when other forms update data. My question is does anyone have experience using this and what are the consequences, if any, in using this to reload/refresh the data showing on the form?
Constantly Update Current Time Display On A Windows Form?
Jun 28, 2011I have a windows form where I want the time to constantly be updated. Right now it will take the current time from when the program was started.
For example, if I started the program at 4:30:29 PM that is what it will show the whole time the program runs.I need it to constantly be updated as the seconds tick by. So, If I started the program at 4:30:29 PM and ran it for exactly 5 minutes, the time displayed then should be 4:35:29 PM.The data being taken in and saved needs a time associated with it and the end user also need to know the current time as the program is ran in full-screen.

I prefer the new record be added only to the first form. I don't want the idea of retrieving the records again from my server.
View 3 RepliesAsp.net - Get A Windows Form Client To Update Everytime A Access Table On Webserver Changes?
Aug 25, 2009I have a form with a list that shows information from a database. I want the list the update in run time (or almost real time) every time something changes in the database. These are the three ways I can think of to accomplish this:Set up a timer on the client to check every few seconds: I know how to do this now, but it would involve making and closing a new connection to the database hundreds of times an hour, regardless of whether there was any change Build something sort of like a TCP/IP chat server, and every time a program updates the database it would also send a message to the TCP/IP server, which in turn would send a message to the client's form: I have no idea how to do this right now Create a web service that returns the date and time of when the last time the table was changed, and the client would compare that time to the last time the client updated: I could figure out how to build a web service, but I don't how to do this without making a connection to the database anyway The second option doesn't seem like it would be very reliable, and the first seems like it would consume more resources than necessary. Is there some way to tell the client every time there is a change in the database without making a connection every few seconds, or is it not that big of a deal to make that many connections to a database?

Refreshing Datagridview From A Second Form?
Jan 24, 2011I am trying to refresh a datagridview from a second form to display newly written data. I have read the posts on this topic and can't figure mine out. My first form opens and you input data into text fields, etc. and then you need to select items from one table to copy and write to a new table. The datgridview on the first form shows the new table, and I have a new form that pops up to select the line items to add. Everything works perfectly except when I close the selection form after selecting lines, I would like the datgridview on the first form to refresh to show that the lines have been selected and displayed in the datagrid.
My data is loaded into the datagridview as so;

Reloading/refreshing Form?
Jan 17, 2012I've been working on this game the past few days, a simple game where two people control different tanks, and shoot each other, very basic so far.The problem I have is when one player is dead. I have the form recognizing each players death by using this code (It's within a timer subroutine)
'Player One Dead
If intPlayerOneHealth <= 0 Then
btnReplay.Visible = True
End If
[code]....
and that code is replicated for every key pressed (Arrow keys, WASD, e, and end). Those booleans are handled in a timer subroutine, where if the boolean is true, they will move/shoot. (Turning the booleans to false is done in the 'Private Sub KeysUp' subroutine)
TL;DR How do I get the game to restart itself when a player dies and hits the replay button?
P.S. I've tried 'Me.Refresh()' as well, and that didn't do anything
